Natural Selection Flashcards
A Deoxyribonucleicacid that is all living cells that contains information
Dna
In a nucleic-acid chain, a subunit that consists of a sugar, a phosphate, and a nitrogenous base
Nucleotide
The amount of adenine in DNA always equals the amount of thymine while the amount of guanine always equals the amount of cytosine they were called.
Chargaff’s Rules
They made a model of DNA that helped explain how it can be copied
Watson and Crick
She used x-rays to make images of Dna and made the process known as X-ray diffraction
Rosalind Franklin
A change in the nucleotide-base sequence of a gene or DNA molecule
Mutations
A characteristic that improves an individuals chance of survival.
Adaptation
A group of organisms that are closely related and can mate to producesoffspring
Species
the process in which inherited characteristics within a population change over generations such that new species arise
Evolution
The remains or physical evidence of an organism preserved by a geological process
Fossils
A historical sequence of life indicated by fossils found layers found in layers of the earth’s crust
Fossil Record
Charles Darwin was a man which made a theory on evolution and natural selection that is very popular today
Darwin
A genetically determined characteristic
Trait
